  • Unlike standard compression springs, die springs are typically made from rectangular or square wire, offering greater strength and deflection capabilities.
  • Many die springs are colour-coded to indicate their load capacity, allowing for easy identification and selection. An expanded range may be available on special order. Please enquire.
  • Designed for long life cycle with constant high end deflections and shot peened to increase fatigue life.
  • Maximum deflection is 37 percent of the length
  • Efficient operating range is 20 to 30 percent of the length
